SpaceX is planning to send up to four private citizens into space to take a trip around Earth sometime at the end of 2021 or in early 2022. The spaceflight company announced an agreement on Tuesday with Space Adventures, a space tourism business that has helped seven different private citizens take trips to (and from) the International Space Station aboard Russia’s Soyuz rocket and spacecraft.

Space Adventures said the price of the mission will not be disclosed, and the two companies were light on other details, like what kind of preparation the tourists will have to go through. The companies did say Tuesday that the tourists will fly in the human-rated version of SpaceX’s Dragon spacecraft and that they will orbit Earth at two to three times the roughly 250-mile height of the ISS.

SpaceX has spent the last few years building and testing out this new version of Dragon as part of a contract with NASA to shuttle astronauts to and from the ISS, after years of using the spacecraft to shuttle cargo to the space station. The private spaceflight company recently completed the second major flight test of the Crew Dragon, as it’s called, which demonstrated the capsule’s ability to escape an exploding rocket.

SpaceX CEO Elon Musk has teased the idea of space tourism as a business for a few years now, though he’s been overly optimistic about how soon that could happen. The company announced in early 2017 that it had accepted undisclosed payments from two customers for a trip around the Moon using Crew Dragon and the Falcon Heavy rocket. SpaceX said at the time that the trip would happen by the end of 2018. But in September 2018, the company announced that it now intends to send one of those passengers — Japanese billionaire Yusaku Maezawa — around the Moon using the company’s massive, yet-to-be-built Big Falcon Rocket. (It’s still unclear what happened to the second customer.)

SpaceX has similarly had to delay the first Crew Dragon flight with NASA astronauts as it worked through the process of certifying the spacecraft with NASA. That flight is now supposed to take place later this year.

Other private spaceflight companies are vying to establish the space tourism market. Richard Branson’s Virgin Galactic and Jeff Bezos’ Blue Origin are in the running, though both of those companies are promising far briefer experiences. Virgin Galactic says it plans to send its first space tourists up later this year where they will experience a few minutes of weightlessness in the company’s plane-like spaceship. Blue Origin is promising customers a similar amount of time in space, though in a spacecraft that’s more similar to SpaceX’s Dragon capsule. (Both of those tickets cost in the neighborhood of $200,000 a pop.)

While little is known about the newly-announced flight, SpaceX has detailed the inside of the Crew Dragon spacecraft that will ferry the tourists around the Earth. The capsule’s interior is a minimalist affair, with just a few suspended seats and an array of touchscreens. The spacecraft is ringed with windows, though they’re not as large as the ones Blue Origin built into its own capsule. SpaceX has also shown off sleek, custom-designed spacesuits and helmets that Crew Dragon passengers will wear. The suits are less bulky-looking than past designs, but are still pressurized, cooled, and flame resistant. They come with touchscreen compatible gloves, and will lock into the seats for the ride up to space.

On Monday, the French trainmaker said it has signed an agreement to acquire Bombardier’s rail business for between €5.8 billion ($6.3 billion) and €6.2 billion ($6.7 billion).

The acquisition, which will be paid for via a mix of cash and shares, will improve Alstom’s “global reach” and its ability to respond to the growing demand for “sustainable mobility,” particularly in Europe, according to a company statement.

Alstom and Bombardier, which is seeking to reduce its debt burden as it nears the end of a five-year turnaround, had earlier confirmed the talks following a report from the Wall Street Journal.

The Canadian company said the deal would enable it to focus exclusively on its aviation business.

The deal will be Alstom’s second attempt to create a European rail company that can compete with the likes of China Railway Rolling Stock Corporation (CRRC), the world’s largest supplier of rail equipment.

A deal between Alstom and Bombardier could create the “European champion” the bloc needs to compete in the worldwide rail industry, said Maria Leenen, CEO of SCI Verkehr, a strategy consultancy focused on the railway and logistics industry.

Last year, EU regulators blocked a deal to combine the train manufacturing businesses of Alstom and its German rival Siemens on concerns that the merger would lead to higher prices for signaling systems and next generation high-speed trains.

The proposal drew comparisons to Airbus, which traces its roots to the consolidation of several European aircraft manufacturers in the 1970s, a structure that helps it compete with U.S. rival Boeing. The rail companies had argued that joining forces was necessary to cope with “growing competition from non-EU companies.”

CRRC is a key rival. The state-owned rail company reported revenue of nearly €21 billion ($23 billion) in 2018, compared to a combined €15.3 billion ($16.6 billion) recorded by Alstom and Bombardier’s rail unit, according to SCI Verkehr.

The Chinese company has been very open about its plans to export more railway products and has already underbid rivals to supply passenger rail cars in Boston, Philadelphia, Chicago and Los Angeles.

It gained an important foothold in Europe last year when it bought German rail company Vossloh’s diesel locomotives business. German authorities are still reviewing the deal.

Leenen said that while China’s presence in Europe is for now “too small to count,” CRRC is pushing into the continent with the political backing of the Chinese state.

Trouble ahead?

Leenen warned the proposed deal between Alstom and Bombardier could also run into trouble with competition authorities, given that together the companies deliver almost 50% of Europe’s regional electric passenger trains.

SCI Verkehr expects to see growing demand for these trains in the next five to 10 years as Europe pushes to reduce its fleet of carbon-emitting cars.

Unions might also be concerned that the merger could lead to plant closures and job cuts, she added.

Other problems may lurk.

“I expect Alstom to factor in the risk of under investment in the plants, low-margin contracts and potential third-party claims” against Bombardier Transportation, Leenen said, referring to Deutsche Bahn’s reported refusal to accept 25 new intercity trains because of “technical defects.”

“Alstom is committed to recover Bombardier Transportation’s full operational and profitability potential,” the company said in a statement. It said that it expects the acquisition to deliver cost savings and boost earnings.

Sixty more satellites for SpaceX’s Starlink broadband network launched Monday on a Falcon 9 rocket from Cape Canaveral, bringing the total number of Starlink platforms deployed in orbit since last May to 300.

More Starlink missions are on tap in the coming months, with the next slated to fly aboard another Falcon 9 launcher as soon as early March.

Monday’s mission began with a burst of flame from SpaceX’s Falcon 9 booster, followed by the release of hold-down clamps to allow the 1.2-million-pound Falcon 9 to climb into a partly cloudy sky over Cape Canaveral’s Complex 40 launch pad.

The 229-foot-tall (70-meter) rocket lifted off at 10:05:55 a.m. EST (1505:55 GMT) powered by thrust from nine kerosene-fueled Merlin 1D engines.

The Falcon 9 quickly cleared lightning towers at pad 40 and steered toward the northeast, sending a window-shaking roar across the Florida spaceport.

Two-and-a-half minutes into the mission, the Falcon 9’s first stage booster shut down its engines and separated, allowing a single Merlin engine on the launcher’s second stage to fire into orbit.

Seconds later, the Falcon 9’s payload shroud jettisoned as the rocket soared into space, revealing the launcher’s more than 34,000-pound (15.6-metric ton) payload package, comprised of 60 flat-panel signal relay nodes for SpaceX’s Starlink network.

While the second stage accelerated into orbit, the first stage of the Falcon 9 descended back through the atmosphere and attempted landing on SpaceX’s football field-sized drone ship “Of Course I Still Love You” holding position nearly 400 miles (630 kilometers) northeast of Cape Canaveral.

But the rocket missed the drone ship and appeared to make a soft landing in the water nearby, according to streaming video from the offshore vessel. The missed landing marked the first time a first stage booster on a Falcon 9 rocket has missed a landing attempt on a SpaceX drone ship since 2016.

The rocket used on Monday’s mission was a veteran of three previous launches and landings. It’s not likely to be reused after landing in sea water.

Two other SpaceX vessels were positioned in the Atlantic Ocean to try to catch the two halves of the Falcon 9’s payload shroud. SpaceX did not announce the results of the fairing recovery attempt, but a company employee said engineers are still experimenting with catching the aerodynamic shroud using fast-moving ships fitted with giant nets. Previous catch attempts have been hit or miss.

Around the same time as the first stage reached the ocean, a SpaceX launch controller announced that the Falcon 9 upper stage had arrived in orbit and was poised to release the 60 Starlink satellites, the mission’s primary objective.

After firing thrusters to enter a controlled spin, the upper stage released retention rods holding the Starlink satellites to the rocket. That allowed the spacecraft — each weighing about a quarter-ton — to fly away from the Falcon 9 as the vehicles soared over the North Atlantic Ocean.

One change introduced Monday different from past Starlink missions was the release of the Starlink payloads into an elliptical transfer orbit, instead of a circular orbit.

SpaceX did not respond to questions from Spaceflight Now on the reason for the change in launch profile, but a host on the company’s webcast Monday said all future Starlink missions will use the new trajectory to inject the satellites into an elliptical orbit after a single upper stage burn.

“We are executing a direct inject of the Starlink satellites into an elliptical, or oval-shaped, orbit,” said Jessica Anderson, a manufacturing engineer at SpaceX. “In prior Starlink missions, we deployed the satellites into a 290-kilometer (180-mile) circular orbit, which required two burns of the Merlin vacuum engine on the second stage.

“Keep in mind the stack of 60 Starlink satellites combined is one of the heaviest payloads we fly, so putting them directly into this orbit requires more vehicle performance and makes recovery more challenging,” she said. “Going forward, and starting with today, we will deploy the satellites shortly after the first burn of the second stage, putting the Starlink satellites into an elliptical orbit.

“Once checkouts are complete, the satellites will then use their on-board ion thrusters to move into their inteded orbits at an operational altitude of 550 kilometers (341 miles).”

According to preflight predictions, the Starlink craft on Monday were programmed for deployment in an elliptical, or egg-shaped, orbit ranging between 131 miles (212 kilometers) and 239 miles (386 kilometers) in altitude, with an inclination of 53 degrees to the equator.

As a result of the orbit change, the Falcon 9’s second stage remained in orbit after release the Starlink satellites Monday. It is expected to passively re-enter the atmosphere in the coming months, instead of performing a controlled de-orbit burn, as the stage did after previous Starlink launches.

Like SpaceX’s previous Starlink launches, the satellites deployed in a tight cluster. SpaceX ground teams will activate krypton ion thrusters and other systems on the satellites to maneuver them into a higher orbit, targeting an altitude of 341 miles for operational service broadcasting signals in Ku-band.

The first phase of SpaceX’s Starlink program, which aims to beam consumer broadband to customers around the world, will include 1,584 of the flat-panel satellites — including spares — in orbit 341 miles above Earth.

SpaceX has approval from the Federal Communications Commission to operate nearly 12,000 Starlink satellites in Ku-band, Ka-band and V-band frequencies, with groups of spacecraft flying at different altitudes with various orbital tilts, or inclinations.

Last year, SpaceX signaled to the International Telecommunication Union that it may seek authority to operate up to 30,000 additional broadband satellites in low Earth orbit, potentially bringing the total Starlink fleet to 42,000 platforms.

But SpaceX says the fleet’s growth will hinge on demand, and the company must launch roughly 20 more missions before completing the first phase of its Starlink network.

SpaceX also needs to test the network and begin selling the Starlink service, and work continues on user terminals to link customers on the ground with the satellite network in space. The company has not announced a price or Internet speeds for its consumer-grade service.

The rapid-fire deployment of Starlink satellites — coupled with plans for other large satellite fleets — has astronomers worried that the proliferation of small spacecraft could impact observations by ground-based telescopes.

The Starlink satellites are brighter than predicted, sometimes reflecting sunlight and becoming as bright as the most luminous stars in the night sky. But the brightest sightings occur only soon after a launch, when the satellites are flying at lower altitudes and are clumped close together.

The satellites are harder to spot as they spread out in the weeks after a launch and begin raising their orbits to their 341-mile-high operating altitude. But scientists caution they will pose a threat to high-power telescopes, such as the U.S. government-funded Vera C. Rubin Observatory under construction in Chile.

The International Astronomical Union — a global body chartered in 1919 to “promote and safeguard the science of astronomy” — said last week that it “considers the consequences of satellite constellations worrisome.”

“They will have a negative impact on the progress of ground-based astronomy, radio, optical and infrared, and will require diverting human and financial resources from basic research to studying and implementing mitigating measures,” the IAU said in a press release.

“A great deal of attention is also being given to the protection of the uncontaminated view of the night sky from dark places, which should be considered a non-renounceable world human heritage,” the IAU said.

At the request of the IAU, scientists from the Vera Rubin Observatory, the University of Michigan, the Centro Astronómico Hispano-Alemán, the European Southern Observatory and the European Space Agency modeled the frequency, location and brightness of satellites in planned “mega-constellations” flying in low Earth orbit.

The IAU said the results of the simulations are preliminary. Some of the simulations assumed more than 25,000 broadband satellites could be deployed in low Earth orbit, in which case between 1,500 and a few thousand spacecraft could be above the horizon at any given time, depending on the observer’s latitude.

The “vast majority” of those satellites would not be visible to the naked eye, according to the IAU. The simulations showed that around 250 to 300 of the spacecraft above the horizon at any given time would have an elevation of more than 30 degrees, the region of the sky where astronomers perform most of their observations.

At astronomical dawn and dusk — when the sun is 18 degrees below the horizon — simulations suggest around 1,000 satellites could be illuminated by sunlight and above the horizon. Around 160 of the illuminated spacecraft could be higher than 30 degrees in the sky at one time, and those are the satellites that pose the greatest threat to astronomical research.

The numbers of illuminated satellites will decrease in the middle of the night, according to the IAU.

In response to astronomers’ concerns, SpaceX launched one satellite in early January with an experimental darker coating. The long-term effectiveness of the external treatment will not be known until the satellite reaches the Starlink fleet’s operational altitude.

Gwynne Shotwell, SpaceX’s president and chief operating officer, said in December the company was in dialog with astronomers about the issue.

“Astronomy is one of a few things that gets little kids excited about space,” Shotwell said. “There are a lot of adults that get excited, too, who either depend on it for their living or for entertainment. But we want to make sure we do the right thing, to make sure little kids can look through their telescopes. It’d be cool for them to see a Starlink. I think that’s cool. But they should be looking at Saturn and the moon.”

The other company on the cusp of launching hundreds, and perhaps thousands, of broadband satellites is London-based OneWeb.

OneWeb has launched 40 satellites to date, with plans to launch roughly 32 to 36 more every month to deploy an initial fleet of nearly 650 spacecraft. But like SpaceX, OneWeb has plans to grow from there.

The satellites owned by OneWeb are smaller than the Starlink spacecraft, and they orbit higher, allowing the company to provide global coverage with fewer satellites than SpaceX. The higher altitude also means they will be dimmer to ground observers, the company says.

“We’re going to do the most we can to mitigate (astronomers’ concerns),” said Adrian Steckel, OneWeb’s CEO. “We’re not visible to the naked eye. We are visible to telescopes. It’s hard to get around some of those facts.”

Scientists have also questioned whether constellations of thousands of satellites broadcasting broadband data will interfere with radio astronomy, which uses giant antennas to listen to faint radio signals generated from distant stars and galaxies.

“With respect to radio frequency … we’ll try,” Steckel said earlier this month. “We’re going to do the most we can. I don’t know if there will be a solution that will make everybody happy. At least we’re in dialog, and we’re trying to get feedback on what can we do.”

The IAU said there is still uncertainty in the eventual impacts of huge flocks of satellites on astronomy.

“At the moment it is difficult to predict how many of the illuminated satellites will be visible to the naked eye, because of uncertainties in their actual reflectivity,” the IAU said, referencing the unknown outcome of SpaceX’s experiments with darker coatings.

“The appearance of the pristine night sky, particularly when observed from dark sites, will nevertheless be altered, because the new satellites could be significantly brighter than existing orbiting man-made objects,” the IAU said. “The interference with the uncontaminated view of the night sky will be particularly important in the regions of the sky close to the horizon and less evident at high elevation.”

The IAU said astronomical impacts during the period of time when Starlink satellites are brightest — soon after a launch — depend on how long the spacecraft are flying at lower altitudes, and the frequency of launches.

“Apart from their naked-eye visibility, it is estimated that the trails of the constellation satellites will be bright enough to saturate modern detectors on large telescopes,” the IAU concluded. “Wide-field scientific astronomical observations will therefore be severely affected. For instance, in the case of modern fast wide-field surveys, like the ones to be carried out by the Rubin Observatory (formerly known as LSST), it is estimated that up to 30 percent of the 30-second images during twilight hours will be affected.”

Formerly known as the Large Synoptic Survey Telescope, the Vera Rubin Observatory will capture deep, wide-field images of the entire available sky, allowing astronomers to learn more about dark energy and dark matter, and detect potentially hazardous asteroids with orbits near Earth, among other objectives.

“Instruments with a smaller field of view would be less affected,” the IAU continued. “In theory, the effects of the new satellites could be mitigated by accurately predicting their orbits and interrupting observations, when necessary, during their passage. Data processing could then be used to further ‘clean’ the resulting images. However, the large number of trails could create significant and complicated overheads to the scheduling and operation of astronomical observations.”

The IAU’s statement last week focused on optical astronomy. Astronomers continue studying the possible interference that signals transmitted by broadband satellites in low Earth orbit will have on radio astronomy.<

The IAU said there are no internationally-agreed rules of guidelines on the brightness of satellites. The group said it will present its findings to the United Nations to bring the attention of world government representatives on the issue.

“The IAU stresses that technological progress is only made possible by parallel advances in scientific knowledge,” the group said. “Satellites would neither operate nor properly communicate without essential contributions from astronomy and physics. It is in everybody’s interest to preserve and support the progress of fundamental science such as astronomy, celestial mechanics, orbital dynamics and relativity.”

SpaceX’s next launch is scheduled for 1:45 a.m. EST (0545 GMT) March 2, again from pad 40 at Cape Canaveral, when a Falcon 9 rocket will loft a Dragon cargo capsule into orbit on a resupply mission to the International Space Station.

Another Starlink launch on a Falcon 9 rocket is also scheduled as soon as March 4 from nearby pad 39A at the Kennedy Space Center.

DETROIT — General Motors says it’s pulling out of Australia, New Zealand and Thailand as part of a strategy to exit markets that don’t produce adequate returns on investments.

The company said in a statement Sunday that it will wind down sales, engineering and design operations for its historic Holden brand in Australia and New Zealand in 2021.

It also plans to sell its Rayong factory in Thailand to China’s Great Wall Motors and withdraw the Chevrolet brand from Thailand by the end of this year.

CEO Mary Barra says the company wants to focus on markets where it can drive strong returns. She says GM GM, -1.50% will support its employees and customers in the transition.

The company said it will scale back operations in all three countries to selling niche specialty vehicles. It also will make the same move in Japan, Russia and Europe, where “we don’t have significant scale.”

“We are pursuing a niche presence by selling profitable high-end imported vehicles supported by a lean GM structure,” International Operations Senior Vice President Julian Blissett said in the statement.

GM said it will honor all warranties in the markets, and it will continue to provide service and parts. Local operations also will handle recalls and any safety-related issues, the company said.

Two NASA-JPL proposals are among the selections: Trident would explore Neptune’s moon Triton, while Veritas aims to map Venus’ surface to determine the planet’s geologic history.

NASA has selected four Discovery Program investigations to develop concept studies for new missions. Although they’re not official missions yet and some ultimately may not be chosen to move forward, the selections focus on compelling targets and science that are not covered by NASA’s active missions or recent selections. Final selections will be made next year.

NASA’s Discovery Program invites scientists and engineers to assemble a team to design exciting planetary science missions that deepen what we know about the solar system and our place in it. These missions will provide frequent flight opportunities for focused planetary science investigations. The goal of the program is to address pressing questions in planetary science and increase our understanding of our solar system.

“These selected missions have the potential to transform our understanding of some of the solar system’s most active and complex worlds,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate. “Exploring any one of these celestial bodies will help unlock the secrets of how it, and others like it, came to be in the cosmos.”

Each of the four nine-month studies will receive $3 million to develop and mature concepts and will conclude with a Concept Study Report. After evaluating the concept studies, NASA will continue development of up to two missions towards flight.

The proposals were chosen based on their potential science value and feasibility of development plans following a competitive peer-review process.

The selected proposals are:

TRIDENT

Trident would explore Triton, a unique and highly active icy moon of Neptune, to understand pathways to habitable worlds at tremendous distances from the Sun. NASA’s Voyager 2 mission showed that Triton has active resurfacing – generating the second-youngest surface in the solar system – with the potential for erupting plumes and an atmosphere. Coupled with an ionosphere that can create organic snow and the potential for an interior ocean, Triton is an exciting exploration target to understand how habitable worlds may develop in our solar system and others. Using a single flyby, Trident would map Triton, characterize active processes and determine whether the predicted subsurface ocean exists. Louise Prockter of the Lunar and Planetary Institute/Universities Space Research Association in Houston is the principal investigator. NASA’s Jet Propulsion Laboratory in Pasadena, California, would provide project management.

VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy)

VERITAS would map Venus’ surface to determine the planet’s geologic history and understand why Venus developed so differently than the Earth. Orbiting Venus with a synthetic aperture radar, VERITAS charts surface elevations over nearly the entire planet to create three-dimensional reconstructions of topography and confirm whether processes, such as plate tectonics and volcanism, are still active on Venus. VERITAS would also map infrared emissions from the surface to map Venus’ geology, which is largely unknown. Suzanne Smrekar of NASA’s Jet Propulsion Laboratory in Pasadena, California, is the principal investigator. JPL would provide project management.

DAVINCI+ (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging Plus)

DAVINCI+ would analyze Venus’ atmosphere to understand how it formed and evolved and determine whether Venus ever had an ocean. DAVINCI+ plunges through Venus’ inhospitable atmosphere to precisely measure its composition down to the surface. The instruments are encapsulated within a purpose-built descent sphere to protect them from the intense environment of Venus. The “+” in DAVINCI+ refers to the imaging component of the mission, which includes cameras on the descent sphere and orbiter designed to map surface rock-type. The last U.S.-led, in-situ mission to Venus was in 1978. The results from DAVINCI+ have the potential to reshape our understanding of terrestrial planet formation in our solar system and beyond. James Garvin of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is the principal investigator. Goddard would provide project management.

Io Volcano Observer (IVO)

IVO would explore Jupiter’s moon Io to learn how tidal forces shape planetary bodies. Io is heated by the constant crush of Jupiter’s gravity and is the most volcanically active body in the solar system. Little is known about Io’s specific characteristics, such as whether a magma ocean exists in its interior. Using close-in flybys, IVO would assess how magma is generated and erupted on Io. The mission’s results could revolutionize our understanding of the formation and evolution of rocky, terrestrial bodies, as well as icy ocean worlds in our solar system and extrasolar planets across the universe. Alfred McEwen of the University of Arizona in Tucson is the principal investigator. The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, would provide project management.

The concepts were chosen from proposals submitted in 2019 under NASA Announcement of Opportunity (AO) NNH19ZDA010O, Discovery Program. The selected investigations will be managed by the Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, as part of the Discovery Program. The Discovery Program conducts space science investigations in the Planetary Science Division of NASA’s Science Mission Directorate, guided by NASA’s agency priorities and the Decadal Survey process of the National Academy of Sciences.

Established in 1992, NASA’s Discovery Program has supported the development and implementation of over 20 missions and instruments. These selections are part of the ninth Discovery Program competition.

The United States government is considering whether to stop General Electric Co from continuing to supply engines for a new Chinese passenger jet, according to people familiar with the matter, casting uncertainty over China’s efforts to enter the civil aviation market.

The potential restriction on the engine sales – possibly along with limits on other components for Chinese commercial aircraft such as flight control systems made by Honeywell International Inc – is the latest move in the battle between the world’s two largest economies over trade and technology.

The issue is expected to come up at an interagency meeting about how strictly to limit exports of US technology to China on Thursday and at another meeting with members of President Donald Trump’s cabinet set for February 28, sources told the Reuters News Agency.

The White House and the US Commerce Department, which issues licenses for such exports, declined to comment, as did a GE spokeswoman. The departments of Defense, State, Energy and Treasury did not respond to requests for comment.

For years, the US has supported American companies’ business with China’s budding civil aviation industry.

The government has provided licences that allow those companies to sell engines, flight control systems and other components for China’s first large commercial aircraft, the COMAC C919. The narrow-body jet has already engaged in test flights and is expected to go into service next year. COMAC is an acronym for Commercial Aircraft Corp of China Ltd.

But GE has received licenses for the LEAP engines since 2014 and was last granted one in March 2019.

The CFM LEAP engine is a joint venture between GE and France’s Safran Aircraft Engines. The proposal to halt the deliveries of the engines was also reported on Saturday by the Wall Street Journal.

Safran did not immediately respond to a request for comment, and French government officials could not be reached for comment.

Flight control systems

Aside from aircraft engines, flight control systems are up for discussion at the February meetings. Honeywell International has received licences to export flight control systems to COMAC for the C919 for about a decade, and one was approved in early 2020, according to a person familiar with the matter.

But future permission for such sales for COMAC’s passenger aircraft may be up for debate. Honeywell also has been seeking a licence for flight control technology to participate in the development of the C929, China’s planned wide-body jet venture with Russia, the person said.

The flight control system operates moving mechanical parts, such as the wing flaps, from the cockpit.

A spokeswoman for Honeywell declined to comment.

An aerospace trade group official said his organisation would like to weigh in on any policy shifts.

“If there are any changes, we would hope they would engage with us, as they’ve done before,” said Remy Nathan, vice president for international affairs at the Aerospace Industries Association.

At the heart of the debate over a possible crackdown on the sale of US parts to China’s nascent aircraft industry is whether such shipments would fuel the rise of a serious competitor to US-based Boeing Co or boost China’s military capabilities.

People familiar with the matter said some administration officials are concerned China could reverse engineer some items, though others say an abundance of LEAP engines in China has not brought that about to date.

If the US were to move ahead with the measure, one person familiar with the matter said, China could retaliate by ordering more planes from Airbus SE, rather than crisis-hit Boeing, which relies on China for a fourth its deliveries.

The Trump administration’s meetings about technology issues also are set to include a discussion of whether to impose further restrictions on suppliers to Huawei Technologies, the world’s largest telecommunications equipment maker, which is on a US trade blacklist. 

Online content should be regulated with a system somewhere between the existing rules used for the telecoms and media industries, Facebook (FB.O) CEO Mark Zuckerberg told global leaders and security chiefs on Saturday.

Speaking at the Munich Security Conference in Germany, Zuckerberg said Facebook had improved its work countering online election interference, and expanded on his previous calls for regulation of social media firms.

“I do think that there should be regulation on harmful content … there’s a question about which framework you use for this,” Zuckerberg said during a question and answer session.

“Right now there are two frameworks that I think people have for existing industries – there’s like newspapers and existing media, and then there’s the telco-type model, which is ‘the data just flows through you’, but you’re not going to hold a telco responsible if someone says something harmful on a phone line.”

“I actually think where we should be is somewhere in between,” he said.

Facebook and social media giants including Twitter (TWTR.N) and Alphabet’s Google (GOOGL.O) have come under increasing pressure to better combat governments and political groups using their platforms to spread false and misleading information.

Zuckerberg said he now employed 35,000 people to review online content and implement security measures.

Those teams and Facebook’s automated technology currently suspend more than 1 million fake accounts each day, he said, adding that “the vast majority are detected within minutes of signing up.”

“Our budget is bigger today than the whole revenue of the company when we went public in 2012, when we had a billion users,” he said.

“I’m proud of the results but we will definitely have to stay vigilant.”

SpaceX has postponed the launch of its next batch of Starlink satellites due to an issue with a valve component on the rocket’s second stage.

The next attempt will be on Monday (Feb. 17), the company said.

The California-based spaceflight company was scheduled to launch 60 of its internet-beaming satellites on previously flown Falcon 9 rocket at 10:25 a.m. EST (1525 GMT) Sunday from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. However, an issue with the rocket caused the company to delay the launch for 24 hours.

“Standing down from tomorrow’s Starlink launch; team is taking a closer look at a second stage valve component. Now targeting Monday, February 17,” SpaceX representatives wrote on Twitter.

When the Starlink mission does launch, you will be able to watch it here and on the Space.com homepage, courtesy of SpaceX, beginning about 15 minutes before liftoff, courtesy of a SpaceX webcast. You can also watch that webcast directly from SpaceX here.

Poor weather conditions at the recovery zone previously pushed the launch into the weekend. SpaceX completed its prelaunch testing for this mission on Friday (Feb. 14), and the company originally hoped to get the rocket off the ground on Saturday, but a quick look at the weather report indicated Sunday was a better date.

The two-stage Falcon 9 rocket launching this Starlink mission has flown three times before. It previously lofted two commercial Dragon resupply missions (CRS-17 in May 2019 and CRS-18 that July) as well as a hefty telecommunications satellite in December.

Following the successful launch, the rocket’s first stage is expected to touch down on a SpaceX’s drone ship landing platform “Of Course I Still Love You” in the Atlantic Ocean, marking the company’s 50th booster recovery.

SpaceX is also attempting to recover the payload fairings and have deployed both of its nose cone-catching ships to the recovery zone.

Each fairing comes with a $3 million price tag, and the company says that if GO Ms. Tree and GO Ms. Chief can snag falling fairings, the company can refurbish them with minimal effort and fly them again. This will ultimately drive down launch costs, SpaceX CEO Elon Musk has said.

To date, GO Ms. Tree has three successful catches and GO Ms. Chief is still waiting for its first.

A cargo ship rocketed toward the International Space Station on Saturday, carrying candy and cheese to satisfy the astronauts’ cravings.

Northrop Grumman launched its Cygnus capsule from the Virginia seashore. The nearly 4-ton shipment should arrive at the orbiting lab Tuesday. It took three tries over the past week to get the Antares rocket off the pad, with it finally taking flight at 3:21 p.m. — an auspicious 3-2-1.

“Awesome launch,” Joel Montalbano, NASA’s deputy space station program manager, said once the capsule reached orbit.

Besides the usual experiments and gear, the capsule holds cheddar and manchego cheeses, fresh fruit and vegetables, chocolate and three kinds of gummy candy expressly requested by the three station astronauts: Skittles, Hot Tamales, and Mike and Ike’s.

Periodic supply runs by Russia, Japan and NASA’s two private shippers, Northrop Grumman and SpaceX, usually provide more than experiments, equipment, clothes and freeze-dried meals. The capsules also bring family care packages, as well as fresh food to offset the run-of-the-mill station grub.

This latest delivery should have arrived well before Valentine’s Day. But last-minute equipment concerns at the Wallops Island launch pad halted last Sunday’s countdown for the Antares rocket, then bad weather moved in. Dangerously high wind scuttled Friday’s attempt.

This was the company’s 13th space station delivery for NASA. The Cygnus capsules get their name from the Swan Constellation.

This particular Cygnus has been christened the SS Robert H. Lawrence in honor of America’s first black astronaut. Lawrence, an Air Force major, was chosen in 1967 as an astronaut for a classified military space program known as the Manned Orbiting Laboratory. He was killed five months later in a plane crash and never flew in space.

The space station is now home for Americans Jessica Meir and Andrew Morgan and Russian Oleg Skripochka. Morgan has been up there since July and the two others since September; they’ll remain on board until April. Three other astronauts returned to Earth earlier this month.

Until astronaut launches resume from Florida — possibly by SpaceX this spring — the station crew will be limited in size to three. NASA astronauts now launch on Russian rockets from Kazakhstan.

Boeing, NASA’s other commercial crew provider, is struggling with software problems in its astronaut capsule. A December test flight was marred by coding errors.

Astronomers will sweep the entire sky for signs of extraterrestrial life for the first time, using 28 giant radio telescopes in an unprecedented hunt for alien civilisations.

The project is a collaboration between the privately-funded Seti Institute and the Very Large Array observatory in New Mexico, one of the world’s most powerful radio observatories. Gaining real-time access to all the data gathered by VLA is considered a major coup for scientists hunting extraterrestrial lifeforms and an indication that the field has “gone mainstream”.

Normal astronomy operations will continue at the VLA, which was featured in the 1997 film Contact, but under the new arrangement all data will be duplicated and fed through a dedicated supercomputer that will search for beeps, squawks or other signatures of distant technology.

“The VLA is being used for an all-sky survey and we kind of go along for the ride,” said Andrew Siemion, director of the Berkeley Seti centre. “It allows us to in parallel conduct a Seti survey.

“Determining whether we are alone in the universe as technologically capable life is among the most compelling questions in science, and [our] telescopes can play a major role in answering it,” said Tony Beasley, director of The National Radio Astronomy Observatory, which runs the VLA.

The first phase of the project, installing new cables, has been funded by John Giannandrea, a senior Apple executive and trustee of the Seti Institute, and Carol Giannandrea.

The VLA project is one of a wave of upcoming Seti initiatives sketched out at the American Association for the Advancement of Science (AAAS) conference in Seattle on Friday.

Jill Tarter, an emeritus researcher at the Seti Institute, gave updates on Panoseti, a proposed observatory in the prototype stage of development designed to continuously watch a large portion of the sky. If funding is secured, Panoseti will comprise two geodesic domes covered in half-metre lenses, giving it the appearance of a giant pair of insect eyes. The ability to simultaneously watch a vast expanse of sky would make it uniquely suited to spotting transient signals, such as the flash of a distant powerful laser. “To catch that kind of thing you really do want to be looking when the signal comes your way,” said Tarter ahead of her talk.

The veteran Seti scientist said the field had been boosted in the past decade by the discovery that about a fifth of stars host planets in the “habitable zone”.

“Now that there might be more habitable real estate out there than we ever imagined early on … it seems to make this next question about intelligent life more realistic,” she said. “It’s not as far on the fringes as it once was – it’s almost mainstream.”

Others are hunting for less intelligent varieties of alien life. Speaking at the same session at AAAS, Victoria Meadows, who leads Nasa’s Virtual Planetary Laboratory at the University of Washington, described observations planned with the James Webb Space Telescope, scheduled to launch next year.

Three Earth-sized planets orbiting a cool, dim star called Trappist-1 in the constellation of Aquarius will be high up on the hit list. Computer models suggest the Trappist-1 system is among the most promising for finding planets with atmospheres and temperatures that would enable liquid water to exist on the surface.

“The James Webb Telescope will be able to tell us whether they have atmospheres like the Earth or Venus,” said Meadows. “It gives us our first real chance to search for gases given off by life on another planet. We’re basically going to get to study Earth’s cousins.”

Siemion also announced the second tranche of results from the $100m (£76m) Breakthrough Listen Initiative: no alien transmissions have been detected so far.

The latest survey, the most comprehensive to date of radio emissions, included the first search of the “Earth transit zone”. The transit zone search targeted 20 stars in positions where the hypothetical inhabitants of these solar systems would be able to observe the Earth’s shadow flickering across the sun. This method of detection has allowed astronomers to identify thousands of exoplanets and determine whether their conditions are potentially habitable.

“This turns that around and says, ‘What if some other civilisation were watching our sun?’” said Siemion.

If there is, it is either watching quietly or watching from some of the other 200bn stars in the Milky Way.

As the latest technology advances bring scientists a step closer to answering the question of whether anyone or anything is out there, there are still issues to be ironed out over best practice in the event that an alien civilisation is detected.

Stephen Hawking warned against attempting any form of contact, suggesting the outcome for humans would not necessarily be good. Siemion disagrees. “Personally I think we absolutely should and I think without a doubt, we would,” he said. “Part of being human is wanting to reach out into the unknown and wanting to reach out and make connections.”

He is less decisive about what Earth’s message should be, however. “I don’t know … I spend absolutely zero time thinking about that,” he said. “I guess I would just say, ‘Hello’.”
